摘要:

金屬錫（Sn）作為鋰離子電池負極材料具有比石墨負極更高的比容量和更可靠的安全性, 得到了廣泛關(guān)注研究。本文首先簡述Sn基負極的儲鋰特性及其要實現(xiàn)大規(guī)模應用仍要解決的關(guān)鍵基礎問題；接著指出將錫與其他相材料進行多相復合、合理調(diào)控電極材料的物相組成與尺度和分布是一種提高錫基負極材料循環(huán)性能的重要措施。主要綜述了Sn與金屬氧化物（包括嵌鋰活性相、非活性相等）多相復合體系負極材料的研究進展，重點介紹微納金屬氧化物與Sn的協(xié)同作用對復合電極材料電化學性能的改善作用。最后強調(diào)如何進一步提高Sn-金屬氧化物多相復合材料的首次庫倫效率仍是需要深入研究的重要方向。

Abstract:

As a candidate anode material for lithium ion batteries, tin (Sn) has attracted much research attention because of its much higher specific capacity and safety than that of commercially used graphite. This article first introduces the lithium storage properties of Sn-based anodes and their key issues which needed to be solved for practical application. It has been pointed out that combining the Sn with other materials, and tuning the composition, dimension and dispersion of the phases, is an important strategy to enhance the cycling performance of Sn-based anodes. We review the recent research progress on Sn-metal oxide multi-phase composite anode materials, focusing on the influence of synergistic effects between Sn and metal oxides on the electrochemical properties of electrodes. Finally, it has been emphasized that the initial Coulombic efficiency of the Sn-metal oxide composite anodes need to be pay more attention and further improved.
